Sometimes, while working with data, we can have a problem in which we require to gather a data that is of the form of sequence of increasing element tuple with each tuple containing the element N times. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using generator expression + tuple()
The combination of above functions can be used to perform this task. In this, we need to iterate through N using generator expression and construction of tuple using tuple().
# Python3 code to demonstrate working of# N element incremental tuples# Using generator expression + tuple # initialize N N = 3 # printing Nprint("Number of times to repeat : " + str(N)) # N element incremental tuples# Using generator expression + tupleres = tuple((ele, ) * N for ele in range(1, 6)) # printing resultprint("Tuple sequence : " + str(res)) |
Number of times to repeat : 3 Tuple sequence : ((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5))
Method #2 : Using repeat() + list comprehension
This task can also be performed using combination of above functions. In this, we use repeat() to repeat elements N times. And iteration is handled using list comprehension.
# Python3 code to demonstrate working of# N element incremental tuples# Using generator expression + tuplefrom itertools import repeat # initialize N N = 3 # printing Nprint("Number of times to repeat : " + str(N)) # N element incremental tuples# Using generator expression + tupleres = tuple(tuple(repeat(ele, N)) for ele in range(1, 6)) # printing resultprint("Tuple sequence : " + str(res)) |
Number of times to repeat : 3 Tuple sequence : ((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5))
